The frequency of price changes lies between 15% to 19.3% whereas this frequency is between 21% and 27% in the United States. The size of price changes remain large even controlling for sales. The distribution of price changes is dispersed with a lot of large and very small price changes.

Finally, January effects on the level of inflation are substantial.
